Frequently Asked Questions
Check here for some of the most frequently asked questions about Duey.ai
How accurate is the AI Detector?
All AI content detectors are imperfect, including our own. Ours sits well over 90% accuracy on all popular models (GPT-4, ChatGPT, Claude, Gemini, LLaMA, etc.). Important to remember: a detector is itself an AI predicting whether content is AI- or human-written.
What does the AI score mean?
The score is the probability that our model thinks your content was created by an AI. A 75% score means it's 75% confident an AI wrote the text — not that 75% of the text is AI-written.
Will my text be stored or made searchable when I run it?
No. Your text is secure, never stored, and not searchable by any software.
What languages does the AI Detector support?
Currently English only. Contact us if you're looking for additional languages.
Which AI models does the Detector work on?
All popular LLMs including GPT-2, GPT-3, GPT-3.5, GPT-4, GPT-4 Turbo, ChatGPT, LLaMA 2, Claude 2, Claude 3, Gemini, Gemini Pro, Perplexity, Jasper, and others.
What if I get a false positive — my own writing flagged as AI?
False positives happen with every AI detector. Be ready to demonstrate your writing process, including revision history. We recommend writing in a Google Doc since its version history makes that easy to show.
How do I make my content undetectable by the AI Detector?
Either write it yourself or run it through our Humanizer. The Humanizer rewrites AI-generated text into something that reads as human.
